Proto J7290-10M Impact Hex Bit Socket 3/8 in 10mm

Product Description

The PROTO J7290-10M is a 3/8 inch drive impact hex bit socket designed for high-torque fastening applications in mechanical, electrical, and industrial service work. Built around a 10mm hex bit, it delivers direct drive engagement on hex-head fasteners and bolts commonly encountered in equipment assembly, HVAC system components, and structural hardware. The bit length measures 1-5/8 inches with an overall length of 2-23/32 inches, giving the socket reach and clearance in confined spaces. At 0.14 pounds, it is lightweight and easy to handle in extended use. This socket is intended for use with 3/8 inch drive impact wrenches and ratchets used by trade professionals across mechanical and service disciplines.

This impact hex bit socket is suited for residential and commercial service environments where hex-head fasteners require consistent, high-torque removal or installation. Typical applications include equipment panel fasteners, motor mounting bolts, and structural hex hardware encountered in HVAC, plumbing, and electrical installations. The 10mm hex size covers a common metric fastener range used across a broad cross-section of mechanical assemblies. It is well suited for use in tight bays or confined access points where a standard impact socket would not seat properly on a hex-drive fastener.

Key Features

• 3/8 inch drive interface compatible with standard impact wrenches and ratchets
• 10mm hex bit size for direct engagement on metric hex-head fasteners
• 1-5/8 inch bit length provides reach in recessed or countersunk applications
• 2-23/32 inch overall length balances reach and maneuverability in confined spaces
• Lightweight at 0.14 pounds for reduced fatigue during extended use

Compatibility

Designed as an OEM-style impact accessory for use with 3/8 inch drive impact wrenches, air ratchets, and hand ratchets requiring a hex bit socket interface.

Installation Notes

Installation and removal of hex fasteners should be performed by a qualified technician using a rated 3/8 inch drive impact wrench or ratchet. Ensure the tool is powered down or the air supply is disconnected before changing sockets. Confirm the hex bit seats fully in the fastener recess before applying torque to avoid rounding the fastener head. Follow applicable service codes and equipment manufacturer guidelines for fastener torque requirements.
